This was a satisfying conclusion to the trilogy, and a considerable improvement on the middle Book. Our hero heroine increased our powers considerably, in all sorts of ways and with the assistance or family members, but this was balanced by the array of powerful forces arranged against her.
I really like the idea of the long lived powerful family, like the Cullens but with more financial acumen. I liked the development of the Book itself as a character and the way it revealed the deceptions of the congregation was deftly handled, this is indeed a very well realised world and I’m not surprised that the author has sufficient material for the supplementary volume (on my list to acquire, but quite expensive).
I’m happy with the ending, it is a new world that our characters are entering, and our heroine has responsibilities that will stretch and exercise her considerable powers. I don’t think she is fated for a quiet life, but I’m sure she is up to the job.
So overall, despite the disappointment of volume 2, I really like the trilogy overall and may try to find time to watch the TV adaptation as well.
